ATTACHMENT FOR HAT-CLIPPING MACHINES.

Application filed July 8,

To all 'wluym. it 1): my concern.

Be it known that I, JAoK S. Lmnowrrz, a citizen of the United States, and a resident of the. city of New York, in the borough of Brooklyn, county of Kings and'.State of New York, have invented a new and Improved Attachment for Hat-Clipping Machines, of which the following is a full, clear, and exact description.

This invention relates to clipping machines and more particularly to an attachment for hat clipping machines.

In the use of clipping machines for the finishing of velour hats, the small particles of fur or clippings exhaust through an open- "ing in the clipping machine directly to the atmosphere and are a menace to the health of the factory hands due to the fact that the air in the room is ladenwith clippings or the small particles of fur.

The principal object therefore of the present invention is to provide a means in the nature of an attachment which is adapted to be associated with the clipping machine for eilecting the removal and collection of the clippings therefrom.

The invention specifically contemplates a pneumatic means for collecting and depositing these clippings which is in the nature of a hood having an exhaust nozzle designed to communicate with a suction hose, said hood being adapted to be attached to a ma chine without materially altering its structure.

With the above recited and other objects in view, some of which will be more apparent hereafter, reference is made to the tollowing detail description, appended claims and the accompanying drawings forming a part of this application, and in which;

Figure 1 is a plan view of a clipping machine with the attachment in applied position thereon.

Fig. 2 is a longitudinal sectional view therethrough taken approximately 011 the line 2-2 of Fig. 1.

Fig. 3 is an end view thereof. I

Fig. 4 is a detail inverted perspective view of the hood attachment removed from the clipping machine.

Fig. 5 is a longitudinal sectional view through a machine illustrating a modified form of the invention.

Referring to the drawings by characters Specification of Letters Patent.

of reference, It) designates a clipping machine oi the type now in general use for the purpose described. The machine is provided with a revolving cutter 11 arranged in the houslng 10 which is open at-the top and bottomlQ. The bottom is partially closed by the cutter blade 13 which co-acts with the cutter 11. It is the ordinary practice to permit the clippings to exhaust through the opening in the top and in order to overcome and eliminate. the danger and disadvantage of such practice, a hood 15 is provided which covers the open top of the machine. The hood illustrated as one practical embodiment of the invention, comprises a flat base plate 16 having formed as an integral part thereof the crown 17 provided with the laterally projecting nozzle 18. The portion 16 of the hood is adapted to fit. snugly over the top of the machine and is secured thereto by the retaining screws 1!). The portion 16 is provided with enlarged openings 20 therein to accommodate the adjusting screws 21 which serve to adjust the cutting blade 13. In use of the attachment one extremity of a suction hose 22 isclamped as at 23 over the nozzle and the same leads through a suitable suction creating means to a receptacle in which the clippings are deposited when withdrawn from the machine. In the modified form illustrated in Fig. 5 of the drawing. the open top of the machine is covered by a plate 24 and in this instance the handle 25 is centrally bored as at 26 and formed with a reduced nipple 27 at its free extremity for the reception of the extremity of the suction hose 28.

Obviously when the machine and the suction creating means is in operation, the clippings will be pneumatically expelled from the housing and deposited ina suitable receptacle for the purpose, thereby overcoming the disadvantages of a machine which exhausts directly to the atmosphere and the resulting detrimental effect on the operator.

As I do not care to be limited to the precise structural details shown, it is to be understood that the right is reserved to em bodiments other than those actually shown to the full extent conveyed by the general meaning of the terms of the claims as expressed and by modifications in the phrasing of the same.

Having thus described my invention, I

claim 21s new and desire to secure by (Letters Patent In a hat clipping machine including a housing and a rotary knife mounted therein, 5 of a hood adapted to (over the open side of said housing, s-a id hood comprising a flat base having openings therein for the accommodation of the adjusting elements of the machine, a hollow crown formed integrally therewith, and a nipple establishing com- 10 munication from the crown to the exterior, said nipple. adapted to be associated with a suction hose for, exerting a suction on all sides ofthe cutting knife to effect the removal of the clippings therefrom.
